Description

The present invention relates to a storage tank device or the like, mechanically welded, sealed, of parallelepiped shape, able to withstand internal pressure.

The present invention particularly relates to a large tank device, intended to be used for example, without limitation, as a digester of a methanization installation.

The present invention also relates to a mechanically welded construction panel intended for the manufacture of a wall of a storage tank device.

The storage tank device, object of the present invention, is intended to solve various drawbacks usually encountered, both for its final use and for its transport from a place of manufacture to that of its use.

Usually, for the production of a mechanically welded storage tank intended to withstand a certain internal pressure, it is preferable to retain spherical or cylindrical shapes, with however the drawback of a capacity / footprint ratio of less than that of a tank of parallelepiped shape.

On the other hand, for large tank devices, which can have lengths and / or widths of several tens of meters, there is the problem of transport, since this currently requires the use of exceptional convoys by road .

It would however be possible to imagine making a tank device consisting of the assembly of modules, with however the drawback of making a sealed assembly at the destination, and in particular the assembly of said modules while retaining the desired rigidity and achieving sealing.

The present invention aims to provide a storage tank device or the like, mechanically welded, sealed, of parallelepiped shape, able to withstand a certain internal pressure,

The advantages and characteristics of the storage tank device according to the invention will emerge more clearly

of the following description and who refers to the drawings attached, which we represented a embodiment no limiting. In the drawings attached: the figure 1 represented a perspective view of a

part of a tank device according to the invention, FIG. 2 represents an elevation view of a manufacturing element of the same tank device, FIG. 3 represents a cross-sectional view along the axis XX 'of the figure 2, FIG. 4 represents a view in elevation and in profile of a panel according to the invention intended for manufacturing the tank device according to the invention, FIG. 5 represents a front elevation view of the same panel.

6 shows a cross-sectional view along the axis YY 'of Figure 5, Figures 7 and 8 show a partial enlargement of the panel as shown in Figure 5, the panel being, in Figure 8, assembled to the tank device according to the invention, FIG. 8 represents the same panel.

With reference to FIG. 1, one can see a tank device 1 for storage or the like, mechanically welded, leaktight, of parallelepiped shape, able to withstand a certain internal pressure, according to the invention.

This tank device 1 has a bottom 10, a ceiling 11 and side walls 12.

The side walls 12 consist of the assembly of panels 2, one of which is visible in FIGS. 4 and 5, themselves coming from the joining together, in pairs, of profiles 3, represented in FIGS. 2 and 3.

In these FIGS. 2 and 3, we can see a profile 3, which is of the C type, that is to say, as is more particularly visible in FIG. 3, that it has a plane central core 30, laterally bordered on either side by two perpendicular flanks 31, themselves folded at right angles to form returns 32 which extend parallel to the core 30 and facing the latter.

With reference to FIGS. 4 and 5, one can see a panel 2 intended for the manufacture of the walls 12.

This panel 2 comes from the assembly of profiles 3, in this case two, knowing that this number is not limiting.

As can be seen in Figure 6, the two sections 3 of the panel 2 are joined by two sides 31, which creates, due to the folding of a side 31 relative to the core 30, at the junction of the two profiles 3, a natural chamfer 33 allowing the deposition of a weld bead 20 all along so as to ensure the joining and sealing.

It will be noted that it is also possible to deposit a bead or weld points, not shown, in the chamfer 34 created at the junction of the two sides 31 at the returns 32.

It will also be noted, as can be seen in FIG. 1, that the cores 30 assembled two by two are intended to constitute the internal face of the tank device 1, while the sides 31 extend from the external side.

The panel 2 further comprises, at each of its two edges constituted by the close ends of the sections 3, a flat iron 21 arranged perpendicularly and welded to the core 30 and which closes the ends of the sections 3.

With reference to FIG. 7, it can be seen that the flat bars 21 are not secured in the same way to the profiles 3 of a panel 2, depending on whether they are intended to constitute the base or the top of the panel 2.

Thus, the upper flat iron 21 is placed back from the plane of the core 30, on the internal side, so as to form a re-entrant angle for receiving a weld bead 22, while the lower flat iron 21 projects beyond the plane of the core 30 on the inner side, and is welded by depositing a weld bead 23 in the angle formed.

Referring now to FIG. 8, it can be seen that, during the assembly operation of a tank device 1 according to the invention, the panels 2 are secured to the bottom 10 and to the ceiling 11, in this case materialized by metal plates.

The lower flat iron 21 is thus placed on the bottom 10, and is joined there by welding, through the deposition of a weld bead 24 in the angle formed between the lower flat iron 21 and the bottom 10.

The ceiling 11 is placed on the upper flat iron 21, which creates between the weld bead 22 and the ceiling 11, a chamfer in which a weld bead 25 is deposited.

The realization of the walls 12 of the tank device 1 is obtained in beam by the juxtaposition of panels 2, which are welded in pairs in the same way as the profiles 3 of a panel 2 are welded, through depositing a weld bead in the chamfer created between the two contiguous sections 3 of the two panels 2. Furthermore, the flat bars 21 of a panel 2 are butted and welded to the corresponding flat bars 21 of an adjacent panel 2.

It will be noted that, advantageously, with reference to FIG. 4, the sections 3 are provided with holes 35, made with precision in their sides 31, so as to allow an adjustment of their position before joining by welding.

The walls 12, the bottom 10 and the ceiling 11 of a tank device are thus perfectly assembled, and in a sealed manner. Their internal faces are flat, while the sides of the sections 3 constitute not only means for stiffening the walls 12, but also means for delimiting spaces 36 intended to receive, without limitation, means of insulation and / or of diffusion of heat or cold.

The panels 2 according to the invention make it possible to envisage the construction of large-capacity tank devices, at destinations far from the place of manufacture of the panels 10 2.

These panels 2 can actually be transported in containers, and assembled and welded on site.
